DIY: Nissan 370Z Oil change (AK370Z way) Pictures inside

JARblue

Same to you, Curtis I am near Ms. Pint, she's just around the corner. I don't use FB, but I'm on the forum enough

I'm not planning to touch the coolant - generic is fine with me. I picked up Redline's Dexron VI Automatic Transmission Fluid for the power steering - I plan to just swap out the reservoir with the new stuff rather than bleed the whole system. My buddy has gallons of the ATE Super Blue, so we'll use that for brake and clutch I have a post in the What Did You Do With Your Z Today (On-Topic) and will be posting there after it's done, too.

Nice chatting with you

Likewise and thanks for the 411 on power steering fluid. I too have Redline through out the car except for engine oil, I am using a special brand recommended by Terry Dyson of dysonanalysis.com.

I did the tranny and diff today, but we left the brake/clutch for another day since we did it at lunch And I'm going to swap out the power steering reservoir in my garage this weekend. I like Mobil 1 because it gives me an option if I ever have to take it somewhere for oil change, but I like the idea of a specially recommended oil from a professional. Mind if I ask what the brand is and whether they do anything specific for your car vs another car using the same type?

Each car will perform different with different results after a oil analysis with many factors to consider, like geographic location in the USA i.e. if your area is in a very dusty high winds and lots of flat rural land to stir up sand and such. Driving habits, non driving habits like if your commute is so short the oil does not get up to operating normal operating temps like me, commute is 3.5 miles one way, but I make up for on the weekends. Still the condensation that builds up and does not burn off during the short commute. How the engine was originally broken in and what type of oil was used during break in and now during long term use. How often the air filter is cleaned and replaced. How the oil withstands the interval and if it deteoriates or breaks down before the 3750 mile oil changel, to name just a few. Terry Dyson does a full out ADVANCED oil analysis that puts BlackStone (BS) to shame. BlackStone is good, but does not perform the additional tests and Terry provides an mpeg audio file commentary on the tests results and suggestions and definitions of all included in the data from a used oil analysis (UOA) test report. If you know and are educated in reading more in the data that BS provides then you can save money and just go with BS. I have always spent the extra $$ and its well worth it. I can email back and forth for more explanations and trial and error between UOA's. Terry also has additonal recommendations and most important the price includes his assistance in tuning the engine that I cannot go into as that would be taking away from his services, plus each car is different even though make and model are identical. They were not built the same and the metalology within the interanl parts used can differ and wear differently. It's highly unlikely that two Z's with the same oil and such would produce identical UOA's. The situation can be duplicated but alot of conditions have to be the same.

I was one of the first to have a large block engine approved for replacement by Nissan North America (NNA) with my brothers 2006 350Z RevUp engine. During the oil consumption days I started using Terry Dyson and especially after the engine swap he provided alot of break in procedures, pretty well known but some are controversial practices on breakin. In a nutshell alot of RevUp owners went thru two and three engine swaps and some had buybacks from NNA. Mine was good, not perfect, and it turned out like initially discussed on the humungious thread on my350Z which I maintained the opening thread after the original poster sold his Z and went back to Honda S2K. He gave me his password to specifically update the opening post with updates from NNA. I have not updated it since 2009. Terry Dyson helped me with the breakin and other Terry secrets for maintaining a non oil consuming engine. After about 1 year I stopped using his service, price increase and most important my UOA's were stablized with good numbers. I will from time to time send in a UOA sample to keep in check on the wear and especially to see if he has new products or has switch recommended oil. He has been using this brand for many years and still recommends it. But there are other secret mixes of fuel additives that have proven successful in a clean burning engine that he switches up from time to time. It's probably the only reason I would toss him a sample UOA. Or if I see a dramatic oil consumption.

With 44k miles on both 370Z's the bros has 2mm oil consumption on recommended with this oil of 5k oil change interval. So with the increased cost (more than Nissan's esther oil, plus freight factored in) it runs about IRC (about $15-17 per quart) and the oil change interval can be pushed out to 5k miles. I am changing both Z's at same time so I get a break by buying in gallon jugs. The fuel treatment runs me about $115 but that last me on both cars about 1.5 years with every fill up, both cars remember. Single car would last about 3 years. All in all I spend alot on oil BUT it has proven to be worth every penney. IMO...

There is a very informative thread over on my350z forum on oil education by member (Resolute), the link to the thread is below. I did use Mobil 1 on both 350Z's with decent results and after a few UOA's I switched to over the counter Penzoil Platinum Plus I also used this during my intial 1250 mile breakin on the 370Z with a regimental oil change at 75 miles, 250, then 500 miles during the first 3750 miles on the car. Then switched over to Terry Dysons recommended oil.

Another well know website forum is Bob is The Oil Guy......and there are probably several posts about Terry Dyson. He has since opened up his own forum discussion for premium yearly subscription members which come with two UOA's. I just went with the package that has the audio commentary on the UOA which I believe is now up to $150 for the Advanced UOA, that audio file alone is worth it's weight in gold. In additon he now offers for $79 (more in line with BlackStone) a RAW data UOA test results for your own interpretation. The guy knows his stuff and is well known through out the oil industry.

Okay this went alot farther than I had intended so here is the oil I use. Dont laugh the stuff really works and most people say what...that's xxxx oil. But dont laugh I have been using it since 2006 on four Z's and it surpasses many off the shelf oil. Now there is still the german brand of Castrol that is hard to get which had great results on 350Z's. Remember each car is different as I outlined only some of the differences above. Resolute's thread on my350Z goes more into detail on the differences of engines.

My oil consumption has been 8mm per oil change interval (OCI) of 5k miles. Pretty good, it's higher because I was rougher on the breakin and run higher revs than my brother's 370Z at 2mm per OCI.

So here is the linky.....I use the 5w-40...again it's more than just the oil that keeps my engine strong and clean with low oil consumption and most important the wear on the metalology.

I am familiar with some but certainly not all of that material. Very interesting Great, informative post, so thanks for that. I have some reading to do

Yeh I have wanted to for some time now spill my beans on the ever flaming topic "Not another oil thread" . I may just copy this post or link it over on the oil Consumption TSB thread on this forum as some good 411 on any member looking for more info (not that there isalready too much out there already) but spoken in a different language. I know first hand, as I have read some posts on the topic and realize I need a degree as a tribilogist to understand it. Let me know if you need any other info non disclosed above in a pm on fuel additives.

Has anyone picked up o nthe fact that the z has an aluminum block and head... Therefore the filter mag is a waste of money.

LinPark

Aren't there other non-aluminum parts inside the engine that could break down?

JARblue

I believe there are a number of non-aluminum parts in the engine. I'm pretty sure the cylinder sleeves are ferrous, and then there are other parts such as crank, rods, rings, cams, rocker arms, etc...

Nope, there is a good amount of ferromagnetic metal that gets into the oil pan. The proof is on my magnetic drain plug.

Would going with a slightly bigger filter cause any type of damage to our engine?

mr300zxc

I just did my first oil change and use the 9E filter from Nissan, the parts manger is also a friend told me that's all they stock anymore.... it's just a little longer then stock and hold little bit more oil..

eastwest2300

I agree with that, I'd rather have the filtermag on than not.

So I've been getting oil changes at the dealership and about to reach 30k I want to switch to motul, is it necessary if i daily drive my car?

JARblue

There are only about a billion threads on that topic, not to mention an entire forum called Bob the Oil Guy. Short answer: no.
